Keywords :
Clear Gel Toothpaste Silica
PRODUCT DETAILS
1. Product Advantages
Our clear gel toothpaste silica is specially developed for premium transparent gel toothpaste and strictly complies with GB/T 32673-2016, FDA and FCC standards. Manufactured via high-purity spherical hydrated silica technology, the refractive index is precisely controlled within 1.45–1.47 to closely match the liquid phase system of toothpaste, delivering high clarity and crystal-clear appearance with light transmittance above 90%.
This material integrates abrasive cleaning and thickening stabilization functions. Its RDA value ranges from 50 to 120 to meet the cleaning requirements of transparent toothpaste. It can form a stable transparent gel network and prevent water separation, stratification and whitening of paste during long-term storage. Featuring high sphericity and narrow particle size distribution, it provides a smooth paste texture free of gritty sensation, making it a core functional raw material for high-end transparent gel toothpaste.

6. Frequently Asked Questions
Q: Why cannot ordinary silica produce transparent toothpaste? A: The key to transparent toothpaste lies in precise matching between silica refractive index and that of the liquid phase system. Conventional silica suffers from unstable refractive index and broad particle size distribution, which causes light scattering and results in whitening and opacity of paste. Our product achieves high transparency through precise control of refractive index and spherical particle morphology.
Q: How to determine the dosage of clear gel toothpaste silica? A: Typical dosage ranges from 15% to 25%. The exact addition amount shall be adjusted comprehensively according to humectant type & content, target transparency and viscosity. Our technical team offers formula guidance and sample testing to help customers achieve optimal transparency performance.
Q: Will the transparent toothpaste turn cloudy during long-term storage? A: No under proper storage conditions. The transparent gel system formed by our silica boasts outstanding stability. No water separation, stratification, whitening or turbidity will occur within shelf life, guaranteeing consistent appearance throughout the sales cycle.
